Having run sfc following Brinks's great tutorial several times now, and looked at the "SFC Details.txt" I have found out that the SFC cannot replace many of my corrupted files due to the
source files being corrupted..
I have run SFC from the desktop about a dozen times, and from the boot about the same amount of times, but it will repair no further due to these source files being somehow mysteriously corrupt.
The resulting message in SFC states that "Windows resource protection found corrupt files but was unable to fix some of them.." in the SFC Details text, the reason is that the source files are corrupt too.
I should point out that although there are a few corrupt/damaged files that SFC is picking up, W764 seems to be ticking over nicely and the corrupt files seem to be stuff like chinese language packs, games of chess etc. and nothing seems to be disfunctional in my daily use of the OS.
However just knowing that something isn't quite right about the system as a result of the SFC showing them up has me now set on fixing it.

- Am I now up the proverbial creek without a paddle? There are quite a lot of corrupt source files in the report.
It seemed to me that if you could "Point.." SFC to a different place for those replacement system reserve files (Like you used ta cud in XP..) then maybe I could snaffle an non-corrupt copy of W764's System reserve folders and SFC could use that as it's source..
Wouldnt it be great if there were an online copy of those files that you point SFC too? - Dream on. This is Real Life.
I do prefer to repair as opposed to re-installing and if anyone has thoughts along these lines, I'd be happy to get started on thrashing a plan out to tinker with SFC's reserve files if it's even possible.. ?
